advice on changing vale stem seals

While you're in there, make sure the pieces of umbrella seal didn't block the return holes. You can tape a small diameter hose that will seal off on the return holes to a shop vacuum, and suck loose debris out from the top side of the holes. If they flow well you should good.
 
well odd news, no real affect on my smoking problem. still smoke at idle, and a cloud on acceleration then quit, no smoke. its all from #6 cylinder, that plug had oil all over it again, and the other 3 plugs pretty clean.

so i dont know ??? how is oil getting in to #6 and only at idle? can the intake gasket leak oil in ?
would an oil control ring not function at idle, then be ok at all other RPM ?
 
as for the leak down, when i replaced the valve seals on that cylinder i had compressed air on that cylinder to hold up the valves. no air got past the valves, because none came out the intake or the exhaust, and nothing got in to the radiator, no bubbles, i had the heater hoses off, noting came out of them, however air did get in to the crank case, could hear it and it would cycle the compressor on

It's getting past rings then !
 
What is the condition of your PCV system? Try disconnecting the PCV valve from the vacuum and plug . Start and retest.
Intake manifold gasket leak?

Rings always pass some air while pressurizing the cylinder.
 
Poor mans compression test.
Disconnect the coil wire from the cap and ground the end to the block or other engine metal.
Crank the engine. The sound should be consistent pitch if all cylinders are even. If you hear a consistent rhythmic up speed as you crank the engine, you have one or more low cylinders. If it is smooth and consistent as each cylinder comes up on compression they are OK.
